GATE.

SPECIFICATION forming part of Letters Patent No. 657,719, dated September 11, 1900.

Application filed March 30, 1900. serial No. 10,843. (No modal-3 To a w/wm it may concern.-

Be it known that I, CLAUDE H. WILLIAMS, a citizen of the United States of America, residing at San Francisco, county of San Francisco, and State of California, have invented certain new and useful Improvements in Gates; and I hereby declare the following to be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a part of this specification.

My invention relates to what are called automatic or self-acting gates arranged to be opened and closed by passing vehicles, also by mounted or foot passengers, and to a peculiar type of these gates that do not swing, but move transversely in a vertical plane by means of their gravity.

My improvements consist in mounting such gates on rollers or wheels that rest and move upon pivoted tracks or running-Ways, the inclination of which is changed by actuating or tripping devices set. in the roadway and operated by passing vehicles, also actuated or opened and closed by hand by mounted or foot passengers.

My improvements also include means of latching and unlatching such gates both automatically and by hand, the manner of constructing frames for the gates and mounting the same, and various features of a constructive and operative nature that will be fully disclosed and explained in connection with and by aid of drawings herewith that form a part of this specification.

The objects of myinvention can be stated as follows: to provide an automatic or self-acting gate and mountings that can beintegrallyconstructed and self-contained and that can be erected by the unskilled; to relieve the main posts and framing from lateral strain caused by the weight of the gate, as when swung; to provide a gate in two sections either of which can be moved independent of the other one; to arrange the gates so they may be with equal convenience opened by passing vehicles or mounted or foot passengers, and to arrange the various parts in such manner as to be protected from injury by the traffic.

To these ends and to apply my invention in practice I employ devices as illustrated in the accompanying drawings.

7 Figure I shows a front elevation of a double taken near the middle of the roadway, showing underground tripping-gearing. Fig. IV is an enlarged side view of the devices to trip or open gates. Fig. V is an enlarged edge I view of the gate-operati ngdevices and latches,

showing also a portion of the gate. Fig. VI

is a perspective view of the tripping device. Similar numerals of reference are employed througout to designate like parts.

The gates 1 and 2 are of the ordinary construction, adapted to pass through the slotted posts 3 and at right and left to the open position shown in II. The gates 1 and 2 are mounted on rollers 5, that rest upon the bent or angular ways 6 and 7, pivoted at 8 and 9 in the main posts below thcsurface of the ground 10, as seen in Fig. I, where the gates and their supports are shown in a closed position.

To open the gates for a vehicle, the pivoted ways 6 and 7 are tilted into the position shown by dotted lines in Fig. I, setting the inner ends at an inclination, so the gates l and 2 will by their gravity roll back to the open position, as shown in Fig. II. When the gates are closed, as in Fig. I, they are held by latches 11 and 12, that engage in a plate 13 on the top of the central fixed frame 14, and when the inner ends of the ways 6 and 7 are raised these latches It and 12 are disengaged, leaving the gates free to roll back.

In the case of a mounted passenger, when only one gate is to be opened, I provide a tripping cord or chain 15, extending down from a hand device 40 to one of the latches 11 or 12, so this can be disengaged and one gate pulled back by hand and held until passage is made. The gate as soon as released will automatically return by gravity to its closed and latched position. In the case of foot passengers the operation is the same, except that the gate is held open by hand until passed. In this manner it will be seen that the gates 1 and 2 not being attached to anything except by the latches 11 and 12 are free to be moved independently or together,as may be required.

In the case of a single gate for foot passengers alone it will be apparent that only onehalf of the structure shown. in Fig..I- is required.

To construct the gates and con nected parts, the main posts 3 and 4 and the end orstopping posts 16 and 17, also the central frame 14, are fastened to a sole-plate 18, the structure is closed at the sides by the boards 19 and 20,

.the gates are inserted, and the whole is complete and ready to be set in the earth without the usual skill required in erecting such structures. It will also be seen that the structure tnadein: this: way isconvenient to manufzac ture and transport.

To tilt the ways 6 and 7, difierent kinds of tripping devices can be employed, placed either above or below the ground, as the circumstances of erection may determine; I'n- Figs. II, III, IV, and VI are shown underground devices that have proved successful in use, consisting of the oscillating shafts 26 27 on opposite sides ofthe gate,to-wh;ich are secured the swinging levers 21 22and theradius-bars 2t 25 at the ends of said shafts, acrossthe tops of whichare placed cross-bars 23, extending horizontally across the roadway in the path of passing vehicles. The crossbars 23 are engaged by the wheels of vehicles, as indicated atA in Fig. III, and the lever' 22 ismoved to an inclined position, as shown means of the bent connection 29, attached at the top to ends of the ways 6- and 7.v This movement winds the curved links 30' about the wheel 28, and when a vehicle has passed through a gate it comes in contact with the other crossbar 23. This swings the lever outward from the gate. The connection 32 and links 30' connected thereto turningthe Wheel- 28 in the opposite direction brings the connection 29 down again to the position shown in Fig. III and by the dotted linesat 35- in Fig. IV. The same efiect is produced by a vehiclegoing in the opposite direction. The slack shown in the connections 3232 in Fig. III is necessary in order topermit the levers 21 and 22' to swing when out of action-into-a,

Having thus explained the nature and objects of my invention, I claim- 1. In a gate, the pivoted oscillating Ways'6 The motion of this wheel isand. 7., gates 1 and 2 mounted with rollingbeari'ngs thereon, and adapted to open and close by gravity as the ways are tilted to produce an inclination right or left, the wheel 28 and a connection therefrom to the inner lends of the Ways 6 and 7 whereby the latter are raised or lowered, substantially as speci fied.

t 2. In a gate or gates, a pivoted way or ways on which the gate or gates will automatically move by gravity, the Wheel 28, connection 29 ;attached: to-the inner ends of the running- Ways, and tripping-gearing to turn the member 28 by vehicles approaching or leaving the gate, substantially as specified.

3. In a road-gate, the slotted main posts 3, i4, end posts 16, 17, central frame 14, soleplate 18 pivoted ways 6, 7, movable gates 1, i2, on said? pivoted Ways, wheel 28 connected to said ways, and means to turn said wheel y the action of a passing vehicle, substangtially as specified.

f at. In aroad-gate, the pivoted angular ways :56, 7, gates 1,.2, sliding thereon, oscillating iwheel 28, and curved link 29, between said gwheel and said pivoted ways, the curvature iallowing said link to pass the center of the .Ewheelin both positions of its throw, substangtially as specified.

5; Ina road-gate, the pivoted angular ways 6,, 7, having slots 39 inthe ends thereof, connect-ing member 38 between said ends, oscillating wheel 28, curved link 29 between said oscillating wheel and said member 38, whereby the pivoted ways are moved in unison,

operated by'a passing vehicle, through'tlexible connections leading to said wheel, substantially as speei tied.

6. Ina road-gate, the pivoted angular ways 6, 7, movably connected together at their inner-ends, gates 1, 2, mounted to slide on said ways,automatic latches 11, 12, operating to hold the gates in closed position and to releasethe gates when the ways are tilted, and a tripping-connection 15, whereby a gate can be-unlatched by hand-without tilting the supporting-way, substantially as specified;

6, 7, movablyconnected together at their inner ends, gates moving thereon, oscillating wheel28 with aconnection to said inner ends, to move the same, vertical fixed frame 14, sustaining the wheel 28, cross-cap 13 on said fi-xed frame, recessedto" receive the latches, and automatic latches'll, 12, on said gates, Zenga-ging said recesses. when the gates are closed', substantially as specified.
